There are so many television adverts for mobile phone-buying websites offering cash for old handsets. But the price they pay varies daily, based on the company and the phone. For example, on one day the same 16GB iPhone4 in good condition could earn between £114.07 and £255 (for top condition).
So it really is worth a rummage through your drawers to see if your old handset is worth anything.
